Book Description

For both commercial and domestic use condensing boilers represent a new generation of heating appliance. They can be used in most buildings, new and existing, large and small, with valuable savings in energy. Payback of the additional capital cost over conventional boilers usually occurs within one to five years. There are some cases where condensing boilers are not economically attractive, but these are the exception rather than the rule. This digest summarises selection, system design, installation, commissioning and maintenance and gives advice on economic appraisal.
